St. Mary's Church, Frankfurt (Oder)

The Church of Peace was founded around 1230 but did not receive its final appearance until the 19th century. After the introduction of the Reformation in 1539/40, the church became a temporary store for grain and hay, served as a shelter for the sick and as a powder magazine. From 1656 it was a reformed church. Due to a lack of parishioners after the Second World War, the building gradually lost its use as a church. Today it is used by the Förderkreis Oekumenisches Europa-Centrum e. V., founded in 1994, with the aim of creating an interdenominational meeting centre.

The Neuzelle Abbey was a Cistercian monastery founded in the 13th century. Between 1655 and 1658, Abbot Bernardus had the reconstructed buildings decorated with frescoes and stuccoes by Italian artists. Secularized by the Prussian government in 1817, the monastery's domains passed to the state-run Abbey of Neuzelle, which existed until its nationalization in 1955. In 1996, the foundation of Neuzelle Abbey was re-established as a foundation under public law of the Land of Brandenburg. The church of the Monastery of the Assumption of St. Mary is a pilgrimage church and parish church.

Altfriedland Abbey is a former Cistercian abbey founded in the 13th century. Apart from the ruins of the refectory and the remains of a cloister, the nave is the only remaining building of the monastery, which was secularised in the 1540s as part of the Reformation.
